Gold application

Gold is contained in many different ore types, each requiring a specific processing route for optimal gold recovery.

As a reagent, lime acts in tandem with cyanide as a lixiviant to recover gold from ore. This is because cyanide can only be used effectively and safely at alkaline pH levels of 10 – 11.  

Lime use is essential in all types of gold processing including simple tank leaching, dealing with nuisance copper, copper-gold, heap leaching, refractory gold, lateritic gold, silver recovery from gold plants and telluride-containing gold.
